Abstract
Apparatus and methods for profiling atmospheric temperature, water vapor and/or cloud liquid content utilizing passive microwave remote sensing are disclosed. The apparatus includes an antenna for receiving atmospheric microwave emissions having frequencies of interest, a highly stable, tunable frequency synthesizer, and downconverting system receiving selected frequency outputs from the synthesizer and the received emissions and, responsive thereto, providing output signals indicative of the frequencies of interest and representing the profile.
